While fleeing from the Giant, they ran into a group of Acromantula that had joined the courtyard battle. Seeing no other way out, they ran from the spiders across the courtyard past the Giant and into the cloister wall's walkway.

With an Acromantula in pursuit, which was then blown into the Ravine below, the Trio discovered Fenrir Greyback, who attacked and bit Lavender Brown, trying to kill her. Furious and angry, Hermione shot a spell at him and pushed him out through a window and into the Ravine.

The Giant, who had chosen to chase the Trio, destroyed the corner of the cloister walls and the Trio ran on the outer side and into the climax between the courtyard and the Viaduct. The Dementors then tried to join the battle but were driven off by Aberforth Dumbledore's extraordinary Patronus. The Trio then ran to the staircase leading to the Boathouse.
